MACHINE FOR MAKNG ENVELOPS.

Specification of Letters Fatent No. 22,149, dated November 28, 1858.

T0 aZZ whom t may concern:

Be it known that I, MILTON Gr. Porras, of Rockville, county of Tolland,and State of Connecticut, have invented certain new and usefulImprovements in Envelop-Machines; and I do hereby declare that the sameare described and represented in the following specification anddrawings; and to enable others skilled in the art to make and use thesame I will proceed to describe their construction and operation,referring to the drawings, in which the same letters indicate like partsin each of the figures.

The nature of this improvement consists in so constructing a selffeeding machine that when motion is given, it will take one sheet ofpaper at a time, paste, carry it forward, fold, press, and deliver it inthe required number for a package separated from the others.

Plate l, is an isometrical view of the front side and end of themachine. Plate 2, is a front side view occupied by the person attendingthe machine. Plate 3, is a top view. Plate 4t, shows the shape of thecams to produce the required result.

A, is the frame work, A is a metallic plate, constituting the top of theframe, and to which the upper working parts are secured; B, is theoperating shaft, crosswise the machine; B is a shaft, lengthwise of themachine, connecting the two, and operating together by means of bevelgears a; the darts upon the gears indicate the direction of motion. Uponthese two shafts are arranged all the cams, and by them are produced allthe motions and results of the machine; each occupying' the positiondesignated by their number in red ink, viz. commencing on the left handside atthe end of the shaft B.

No. 6, is the first cam and operates the pasting and paper liftingarrangement. No. 7 is the second cam and moves the carriage No. 2, isthe third cam and operates one of the folding flaps, marked l. No. 3, isthe fourth cam and moves one of the folding flaps, marked 3. Thencommencing on the left, on the shaft B, No. l is the first cam, andmoves one of the folding aps, marked 4. No. 5, is the second cam andlifts the envelop after it is folded and pressed, ready to be takenaway. No. 9, is the third cam and operates the nippers that take theenvelop after it is folded, and brings it forward and drops it on theapron. No. 8, is the fourth cam, and carries the paper down and formsthe envelop. N et, is the fifth cam, and moves one of the folding flaps,marked H.

C, C, C, are three supports, in the boxes of which are placed shafts D,Z).

E, is a stand having guide pins o.

F, is a jack which dips into the paste box and is steadied by the guidepins, fv, and carried forward by the arm c, on the shaft, l), directlyover the paper on the table, G, and over the iiy CZ, (which is securedto the shaft, o, by an arm Z, projecting therefrom).

H, 1s a paper carrier arranged and sliding back and fort-h upon rods I,having two ribs, f, guides, e, and wedge shape catches m; so that asitmoves back, slides under the paper lifted by the jack they will catchthe paper as laid down from the jack on to the table G, by the fly d,caused by the action of the pin g, striking the arm, Z, in shaft Z), inits backward movement.

I, is a fixed table on which the paper is placed before it is pushedforward to the former, having two grooves, z', which diminish toward theright, on the front end of the carrier, H, is a crooked shaft, 0, havingspring fingers, fn, which drop into the grooves, z', and push the paperforward as the carrier, H, advances with another piece of paper on itsbed.

j are arms projecting forward from the shaft, 7c, and resting on theedge of the table, L'so that as the jack lifts the paper and it is laiddown on the carrier by the fly, caught by the catches, fm, is carriedforward on to t-he table, and held by the arms, j; as the carrier tablereturns, the lingers, n, are lifted by the dropping arm, w, loose on theend of the finger shaft, 0, riding back over a stud, p, fixed on theopposite side of the machine so as to lift the fingers in the backwardmotion over the paper and drop them in the grooves just back of the endof the projecting arms, y', and taking the paper therefrom, and as theymove forward gradually coming together true, the paper for the former.

J, is a standard or supportfor the shaft K, having bearings in the upperend and in the bed, to guide it in an upright position.

L, is a box just the size of the envelop required to be made, securedupon the bed plate, M; N, is a rising bed, tted into and just fills thebox, L.

O, are folding flaps formed on the end of the shafts, secured in boxeshaving pinion gears on said shafts, by which they are operated, saidflaps are made of such shape as will allow them to turn down upon thebed at, or nearly at, the same time, Without coming in contact Wit-heach other, and having a half circle ai, formed on the back edge of thesurface of the fiaps in exact line With the center of the shaft, andplaned upon the center on which the bearings are turned, so that thesurface of t-he half circle fr Will turn closely up to the bed N, and asthe flaps turn down onto the bed N, the angle between the half circle mand the face of the flaps O, Will nicely fit to the corners of the bedN. Thus When the plunger R, carries the paper doivn between the halfcircles m, and as it rises, the folding iiaps turn over the folds of theenvelop and press them down between the half circles :e a', thus givingthe envelop a perfect form. The shaft I, is secured into the bed, N,thence by another connection to the cam No. 5. A lever Q, connection, r,balancing Weight, u, are employed to aid in the lifting of the bed, N.

R, is a plunger having a shaft, S', (and connected to the shaft, K, byan arm, T,) passing up through an arm projecting from the standard, J,and is thereby kept in eX- act line With the bed below, and is of thesame size. Said plunger is provided With springs so that they Will bejust even with the surface When pressed down on the bed below, and Willseparate the paper therefrom as the plunger rises before the folding andpressing is finished; thus by a connection from the shaft K, to the camNo. 8, the plunger, R, is operated.

NOW as the fingers are pushing the paper forward, and the bed N, isrising, and the plunger descending, catches the paper in exact time andmanner and together, and carries it down, forms, and the plunger rises;the folding flaps, 0, by means of the rack arms, s, pinions, l', andconnections to the cams Nos. l, 2, 3, and Li, as described, operate justin time, fold and press, and the bed rises with the nished envelop tonearly the starting point, and is caught by the nippers, T', and takenout on to the apron, W, arranged with a catch Wheel, t, and guard, y, sothat it will move one tooth only at a time until a package oftwenty-five is counted oif, When the moving lever, u, which always ridesback on the guard, y, over several teeth but does not move but one toothuntil one revolution of the Wheel, t,

which brings up one tooth, g, longer than the others; consequently theWheel receives the full motion of the lever, u, Which separatestwenty-five from the others; the platform, G, upon Which the paper isfirst placed is moved by a common arrangement for such purposes,movingone tooth of a Wheel at a time, thus keeping up a slow rise of thebed as the paper is taken therefrom.

I am aware that slight variations in the shape, arrangement, andconstruction of this machine, may be made Without essentially lchangingits principle of operation. I do now, intend to change somewhat theshape and arrangement of some of the parts, so as to increase the speed,Work off more envelops in a given time; as I have for a long time beenat Work perfecting, so I expect still to make some slight changes and improvements Without materially altering the principle of operation asherein described. Thus by this arrangement of mechanical movements I amenabled to oroduce a perfectly formed envelop in tie most rapid mannerand with the least possible Waste of stock.

What I claim therefore and desire to secure by Letters Patent isl. Theshape essentially of the cams Nos.

1, 2, 3, 4C, 5, G, 7, 8, 9, for the purpose set forth.

2. The employment of the jack, F, arm, c, operating as described topaste and lift the paper, and the fly, b, to separate it there-.

from on the carrier, II, as described.

3. The carrier, II, shaft, 0, fingers, n, arm, w, stud, p, catches, m,and arms, y', for the purpose as described.

4. The combined action of the bed, N, with the plunger, R, for thepurpose as described; also t-he employment of the springs in theplunger, It, for the purpose as described.L

I claim the folding flaps O, projecting from the center, or nearly so,from the end of a shaft, or shafts, and having their bearings on oneend, or on each end thereof Whether with or Without the half circle wsubstantially as shown and described.

6. The construction and arrangement of the catch Wheel, t, With a longtooth, g, and guard, y, for the purpose as described.

7. The arrangement of the' nippers, T, operating in the manner and forthe purpose described.
